选择试验模型法在澳门固体废弃物管理中的应用

环境物品或环境服务的经济价值评估是环境经济学研究的前沿领域.选择试验模型法是目前国际上用于评估环境物品经济价值的一种新方法.本文以澳门的固体废弃物管理为例,探讨选择试验模型法在澳门进行环境物品经济价值评估实践的可行性.在专家咨询和小组讨论的基础上,确定垃圾分选和回收、垃圾收集频率、减小垃圾收集过程中产生的噪音和垃圾处理费为澳门固体废弃物管理的4个属性.在对澳门6个堂260名居民进行随机抽样调查的基础上,分析了澳门固体废弃物管理不同属性的价值以及固体废弃物管理不同替代方案的相对价值.结果表明,实行垃圾分选和回收利用以及减小垃圾收集过程中产生的噪声是澳门今后固体废弃物管理的合理选择.

Choice Experiment Method and Its Application to Solid Waste Management in Macao

Economic valuation of environmental goods or services has been becoming a research frontier and hotspot of environmental economics in the world.Choice experiment(CE) is a relatively new method that can be used to value the economic benefits of environmental goods or services.This paper reports an attempt to apply the CE method in Macao that aimed to understand Macao residents' preferences for solid waste management programs.A random sample survey of 260 respondents in Macao was conducted during the summer in 2004.Survey data was analyzed using multinomial logit models.Results from 260 in-person interviews indicate that Macao residents preferred waste segregation and recycling at source and noise reduction during waste collection and transportation.The study concludes that CE is a reliable tool in the analysis of respondents' preferences for the development of suitable solid waste management programs in Macao.
